• Exemples d’apports de l’intelligence artificielle (IA) pour l’envirotypage et Phénotypage numérique des plantes · 2026

  Résumé de la publication : The characterization of plants and their environment is changing scale with the development of digital plant phenotyping tools and methods. Phenotyping and envirotyping tools are more accessible, enabling multi-scale observation of plants and their environment—even molecules—through multi-plot observation via satellite. At the…

• Cover crops and intercropping help reduce nitrate and pesticide leaching in low-input systems · 2026

  Résumé de la publication : Context: The agroecological transition offer opportunities to reduce agriculture's environmental impacts by reducing reliance on synthetic fertilisers and pesticides. Crop diversification, in both time and space, is a key strategy including extended crop rotations, intercropping, and cover crops. Yet, relationships between reduced…

• A loss-of-function allele fixed during domestication reshapes nectar chemistry, microbial diversity, and pollinator visits · 2026

  Résumé de la publication : Nectar is a hub for plant-pollinator interactions, yet gene-level causal links between plant genetic variation, pollinator foraging, and nectar microbial assembly remain poorly resolved. Using near-isogenic lines, innovative field time-lapse monitoring of pollinator visits, and long-read amplicon sequencing of nectar microbiota, we…

• High-throughput phenotyping of wheat ear surface area and ear density in the field · 2026

  Résumé de la publication : Ear density (D e ) and ear surface area (S e ) in cereals are important traits for adaptation to low inputs and climate change. Here we propose a high-throughput field phenotyping method to estimate these traits using nadir and 45 •…

• Assessing plant area index and 3D plant area distribution in wheat canopies from a terrestrial LiDAR system for high-throughput plant phenotyping · 2026

  Résumé de la publication : This study investigates a new methodology to estimate plant area index (PAI) and its spatial distribution from 3D point clouds acquired by a system of 3 LiDARs (2 nadir-viewing and one at 45°) mounted on the Phenomobile Unmanned Ground Vehicle designed for…
